To all 1071 0777, it may concern 1 1 7 Be it known that I, SAMUEL MJJENKINS, a resident of Louisville, 'Jeiferson county, Kentucky, have invented a new and useful Improvement in Lubricating Apparatus, of which the following is afull, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view showing one form of my improved apparatus; Fig. 2 is a partial vertical section showingthe rotary bearing and stem; Fig. 3 is a cross-section slioi'ving the pin for preventing rotation of the stem; l ig; 4: is a sectional side elevation showing the steam pipe and heating and exit pipe portion of the lubricating apparatus; Fig. 5 is a secti'onalperspective"of the lower portion of cylinder; Fig. 6 is a sectional detail view of theworm gear feeding device; and Fig. 7 is a sectional'elevation of the assembled device My invention relates to the lubricating of engines andprimemoversfand is designed particularly tojprovide for the carryingof finely powdered graphite to the working surfaces; although it may be used with'heavy greases without the use of graphite.

In carrying out my invention I provide a pressure device in which the heavy grease is placed and is forced out in a column through a conduit or pipe. At the end of this column' is a heating pipe within which the grease is liquefied and then atomized and fed into a current of fluid in small particles.

The invention is especially adapted for feeding lubricating material into the steam pipe or motive fluid inlet pipe for prime movers.

In the drawing, 2 represents an openended cylinder with a sphericalbottom, and 3 the piston therein, which preferably has a This piston is secured to the lower end of a threaded stem 4, which stem has a spline groove 5 within which an adjustable pin 6 projects to prevent rotation. This pin is secured to a U-shaped frame 7 fastened to the sides of the cylinder. In the upper cross bar portion 8 of the frame is mounted a rotary bearing 9, preferably having bearing balls 10 between it and the frame to take up thrust. On this rotary bearing is secured a worm wheel 11, which is engaged by a worm 12 on shaft 13, mounted in bear- 7 Specification of Letters Patent. Application filed April 27, 1912.

ings on a swinging frame l tpivotally car pin 15 secured to theframe;

ried on a lower a p This swinging. frame carries the shaft 13, on which is mounted a ratchet wheel l6having actuating pawls 17 pivotally mounted l on a ratchet lever 18. slotted'to adjustably receive a pivotal connection with an actuating link 20, which is connected to any suitable reciprocating part of the engine-or valve mechanism.

A spring 24 normally holds the worm in engagement with theworm wheel, and these. parts are disengaged automatically at the end of the feed stroke of the piston by a tappet 25-secured to the upper end of the threaded stem and engaging a cam projection 26 at the top of the'swinging frame. These parts may also be disengaged by a thumb latch 27 "on the frame 7, which is weighted to fall into disengaging position and lock the worm apart from the worm wheel after the tappet' 25has forced it back.

In fillingjthe cup with a new charge, the wormis disengaged from the worm wheel by the thumb latch'and'the piston is turned up by hand by rotating" the worm wheel in the opposite direction. The charge of grease is then inserted, the piston lowered upon it, the worm engaged with the worm wheel, the thumb latch thrown into. ofi position, and the grease is 'forced forward by a series of pulsations received through the ratchet mechanism, ratchet drive and screw.

From the bottom of the cylinder leads one or more feed pipes or conduits 28. In the intermediate part of these, I may employ a sight feed device, as shown at 29 in Fig. l, though this may or may not be used,

This ratchet lever is as desired. The end of the feed pipe 28 is preferably secured in the side supply pipe 30,

of the steam and to 1ts inner end is se cured the heating and exit tube 81, which a pressures to the viscous or solid grease in I the cup and force the column forward into the heating and exit tube. As the grease enters its tube it becomes heated and liquelied, and will exude from its open end and become atomized and carried forward by the I form,,and then deposited upon the Working surfaces of the Valves and motor and give highlyeflicient lubrication thereto.

The advantages from 1 the improved apparatus, by which heavy grease maybe fed in finely divided atomized charges to the Working parts of a motor with or without graphite suspended therein as d siredl preferab y employ the graphite, however, as; it is a highly efliie t lub ic nt for su h purposes The g ease which I ordinar ly employ, is a mixture ofcyl n-d s ock or val e .oil, graphite and paraffin, These are mixed in liquid allowed to cool, giving a yis- .oous or solid cake. c'lhemixture whichl pr ef oe p oy is set fo h in my oop nding application.

By reason of the openeend form of the cylinder 2, and the facility with which the pressure devices may be remoyed therefrom, the apparatus can be very quickly ref charged.
